I did several searches, so I hope I didn't miss a post elsewhere!

I have a 2006 Cayenne with a PCM. It has Sirius radio and I lose my signal all of the time, including on open highways with no obstructions whatsoever. I wanted to check the antenna connection or perhaps install a better antenna.

My question is, where is the Sirius module on a PCM? The back of my PCM has 2 antennas plugged in at the moment, one connector is black and one tan. I unplugged both figure one was a Sirius antenna, yet the Sirius still worked like a champ making me wonder if thisis a MOST module that is burried somewhere.

Any ideas? I already have my dash disassembled as I am installing a mObridge Bluetooth and I'd love to resolve this at the same time!

Thanks!

It's in the rear spoiler.

The two antennas are the regular Diversity inputs for the radio. The sat goes in thru the multi pin, bottom right next to the MOST plug. If you have had them all out then the Sirius module is inside the PCM itself behind the backplate (or so I was told, mine does not have Sat (04)

If you look at the instructions that came with the Cayenne sirius kit, it spells it all out. I think it's also visible on Renntech.

The antenna, as someone else mentioned is under the rear spoiler. There are three wires connected to it, one pink, one purple, and one white. The control unit is under your rear passenger seat. The antenna is connected to the control unit and the control is connected to the PCM via the most bus. Since you have an 06 you're still under warranty. Before you install a bunch of aftermarket stuff I would take it to the dealer and have it fixed under warranty while everything is still stock.

So the 08' GTS I have has XM Radio... wonder when that changed ?

You could have selected Sirius
